[GRASS-dev] PNG driver - slow?

[Jachym Cepicky]

Hi,

export GRASS_PNGFILE=/tmp/pokus.png
export GRASS_RENDER_IMMEDIATE=TRUE

time d.vect map=soils at PERMANENT
real    0m0.197s
user    0m0.166s
sys     0m0.019s

time d.vect map=soils at PERMANENT color=yellow fcolor=yellow cats=32 width=3
real    0m13.767s
user    0m13.611s
sys     0m0.098s


Why is the second case so slow? Is it a bug in PNG driver? What can I
do, so it is rendered faster?

Thanks

Jachym
